The finite element method (FEM) is commonly used in modeling the electromagnetic field of transformers with high accuracy; however, computation time FEM prohibitively for real-time simulation due to model order. Reducing order helpful improve computational efficiency FEM. proper orthogonal decomposition (POD) an efficient reduce linear but encounters difficulties nonlinear models. In this paper...
This paper compares ray tracing, finite difference time domain, and the event driven transmission line matrix models as tools for making site specific pathloss predictions in cluttered environments. A brief overview of each type of model is presented. The accuracy and computational cost of a ray tracing, FDTD, and event based TLM model are compared for a small, indoor propagation experiment. Th...
In this paper we propose a fault-tolerant architecture for mesh-based network on chips to recover from permanent faults in switches. We add a number of spare links between processing elements and their neighboring switches and some logic redundancy to network elements. Also online fault detection and correction strategies are presented for this architecture. We model and simulate the communicat...
The early events of hepatitis B virus (HBV) infection remain unclear. In 2006, Stoeckl et al. proposed a new entry mechanism involving a translocation motif (TLM) present in the pre-S2 domain of envelope proteins (L. Stoeckl, A. Funk, A. Kopitzki, B. Brandenburg, S. Oess, H. Will, H. Sirma, and E. Hildt, Proc. Natl. Acad. Sci. USA 103:6730-6734, 2006). After receptor binding and internalization...
OBJECTIVES This study compared the survival outcomes, local control rate, and laryngeal preservation rate of various treatment strategies in the treatment of T3 squamous cell carcinoma of the glottis using proportional meta-analyses. METHODS Twenty-five retrospective case-series studies were included in these analyses. Treatment strategies were classified as total laryngectomy (TL), open part...
Abstract A new simple computational tool is proposed for the synthesis of multi-section coupled-line filters based on combined modified planar circuit method (MPCM) and transmission line (TLM) analysis, referred to as MPCM-TLM. Due its fundamentally architecture, presented offers significantly faster optimization – exactly same initial simulation set-up than other costly commercially-available ...
A supercondensed TLM node for modelling inhomogeneous anisotropic media on an arbitrarily graded mesh without using stubs is developed. It requires less storage, computationally is more efficient and can operate on a higher time step then existing TLM nodes. Complete derivation, implementation and validation of the new node are presented in the paper. Introduction Transmission-Line Modelling (T...
INTRODUCTION During HIV-1 infection the B-cell compartment undergoes profound changes towards terminal differentiation, which are only partially restored by antiretroviral therapy (cART). MATERIALS AND METHODS To investigate the impact of infection as early as during primary HIV-1 infection (PHI) we assessed distribution of B-cell subsets in 19 PHI and 25 chronic HIV-1-infected (CHI) individu...
This letter sets out to describe the first results of design process that will lead a new on-line partial discharge location method based on Electromagnetic Time Reversal theory and using Transmission Line-Matrix method. A description basic steps under is given together with modeling procedure used time inverted signal propagation. Finally, ability locate discharges power cables both two observ...
BACKGROUND The contemporary treatment of oropharyngeal squamous cell carcinoma (SCC) is an area of debate. We report outcomes of a minimally invasive approach involving transoral laser microsurgery (TLM). METHODS A consecutive series of patients (n = 153) undergoing primary TLM for oropharyngeal SCC from 2006 to 2013 was studied. Human papillomavirus (HPV) status was determined by p16 immunoh...
